pass” mode. CDR-bypass mode can be achieved by changing the register value in EEPROM-Table 0,
Byte 111, Bit 0.
a. Use bit 111.0 to enable/disable Rx CDR (“1” to bypass and “0” to engage)
By default, the CDR devices shall be engaged on power cycle or module reset.

VIII. Digital Diagnostics Functions
As defined by the XFP MSA
1
, Finisar XFP transceivers provide digital diagnostic
functions via a 2-wire serial interface, which allows real-time access to the following
operating parameters:
Transceiver temperature
Laser bias current
Transmitted optical power
Received optical power
Transceiver supply voltage
It also provides a sophisticated system of alarm and warning flags, which may be used to
alert end-users when particular operating parameters are outside of a factory-set normal
range.
The operating and diagnostics information is monitored and reported by a Digital
Diagnostics Transceiver Controller (DDTC) inside the transceiver, which is accessed
through the 2-wire serial interface. When the serial protocol is activated, the serial clock
signal (SCL pin) is generated by the host. The positive edge clocks data into the XFP
transceiver into those segments of its memory map that are not write-protected. The
negative edge clocks data from the XFP transceiver. The serial data signal (SDA pin) is
bi-directional for serial data transfer. The host uses SDA in conjunction with SCL to
mark the start and end of serial protocol activation. The memories are organized as a
series of 8-bit data words that can be addressed individually or sequentially. The 2-wire
serial interface provides sequential or random access to the 8 bit parameters, addressed
from 000h to the maximum address of the memory.
For more detailed information, including memory map definitions, please see the XFP
MSA documentation
